“…To the best of our knowledge, this is the highest conductivity in the composition of 78Li 2 S•22P 2 S 5 electrolytes ever reported. 26,31,34 Even by Li 2 SO 4 doping, ball milling at high temperature, or some other sophisticated modification, the ionic conductivity obtained by previous work is still only about 1.0 × 10 −3 S cm −1 , which is lower than our result. Using this high-conduction glass-ceramic as electrolyte, and Li 2 S and FeS 2 as the cathode active substances, we prepared all-solid-state Li−S batteries with excellent performance and effectively demonstrated the viability of these glass-ceramic electrolytes prepared via simple heat treatment.…”

“…The ionic conductivity of the sealed pellet sample also increased, but less, to 1.01 × 10 –3 S cm –1 , which was resulted from the appearance of the unknown new phase and the Li 7 PS 6 phase. The ionic conductivity of over 10 –3 S cm –1 is the highest ionic conductivity ever achieved in 78Li 2 S·22P 2 S 5 glass-ceramic electrolytes. ,, The activation energy ( E a ) of the 78Li 2 S·22P 2 S 5 glass-ceramic electrolytes is then determined from the temperature dependence of the ionic conductivity as shown in Figure . By fitting the Arrhenius plots to the equation: σ ∝ exp(− E a / kT ), E a of ∼0.31 eV is determined.…”

Highly Li-ion conductive 78LiS-22PS glass-ceramic electrolytes were prepared by simple heat treatment of the glass phase obtained via mechanical ball milling. A high ionic conductivity of ∼1.78 × 10 S cm is achieved at room temperature and is attributed to the formation of a crystalline phase of high lithium-ion conduction. All-solid-state lithium-ion batteries based on these glass-ceramic electrolytes are assembled by using LiS nanoparticles or low-cost commercially available FeS as active cathode materials and Li-In alloys as anode. A high discharge capacity of 535 mAh g is achieved after at least 50 cycles for the all-solid-state cells with LiS as cathode materials, suggesting a rather high capacity retention of 97.4%. Even for the cells using low-cost FeS as cathode materials, same high discharge capacity of 560 mAh g is also achieved after at least 50 cycles. Moreover, the Coulombic efficiency remain at ∼99% for these all-solid-state cells during the charge-discharge cycles.

“…In conclusion, optimization of each property including ionic conductivity, material stability and interfacial properties with electrodes is the key to optimizing material properties by doping. Oxides including Li 2 ZrO 3 [ 94 ], LiSO 4 [ 95 ], Li 2 O [ 96 ], ZnO [ 97 ], LiNO 3 [ 98 ] and Nb 2 O 5 [ 99 ] can effectively enhance the ionic conductivity performance of SSEs materials by doping. 70Li 2 S-(30 − x)P 2 S 5 -xLi 3 PO 4 was successfully prepared by Huang et al [ 100 ], exhibiting 1.87 × 10 −3 S·cm −1 with a minimum activation energy of 18 kJ/mol when x = 1% mol.…”

The all-solid-state lithium battery (ASSLIB) is one of the key points of future lithium battery technology development. Because solid-state electrolytes (SSEs) have higher safety performance than liquid electrolytes, and they can promote the application of Li-metal anodes to endow batteries with higher energy density. Glass-ceramic SSEs with excellent ionic conductivity and mechanical strength are one of the main focuses of SSE research. In this review paper, we discuss recent advances in the synthesis and characterization of glass-ceramic SSEs. Additionally, some discussions on the interface problems commonly found in glass-ceramic SSEs and their solutions are provided. At the end of this review, some drawbacks of glass-ceramic SSEs are summarized, and future development directions are prospected. We hope that this review paper can help the development of glass-ceramic solid-state electrolytes.

“…Lithium oxyacid salts are promising electrode materials. For example, the addition of lithium sulfate (Li 2 SO 4 ) to battery materials, including solid electrolytes and positive electrodes, improves ionic conductivity and ductility. − Li 2 SO 4 has been incorporated into Li 2 S-based positive electrodes to create nanoscale lithium ionic pathways, resulting in a high capacity. ,, As the composition of lithium sulfite (Li 2 SO 3 ) is similar to that of Li 2 SO 4 , it is expected to also have beneficial effects on cell performance. However, to the best of our knowledge, Li 2 SO 3 has not previously been structurally and electrochemically investigated in the solid state and has only been detected as a decomposed species.…”

Lithium-ion batteries are widely used owing to their advantageous performance characteristics. However, safety issues associated with liquid electrolytes have inspired the development of all-solid-state lithium−sulfur (Li/S) batteries as safe and high-energy-density candidates for next-generation batteries. Lithium sulfide (Li 2 S)-based positive electrode materials exhibit a high charge−discharge capacity and cycle performance. However, because of their insulating nature, ionic and electronic conduction pathways must be created for charge−discharge cycling. In this study, the incorporation of lithium sulfite (Li 2 SO 3 ) to create nanoscale lithium ionic pathways in Li 2 S-based positive electrodes was investigated. Li 2 SO 3 was synthesized and electrochemically characterized for the first time. Li 2 S− Li 2 SO 3 samples were prepared via ball-milling, and the composite positive electrodes combined with conductive additives were utilized as positive electrodes in all-solid-state batteries. The cells with Li 2 SO 3 exhibited a high reversible capacity, excellent rate performance (1C rate), and a long cycle life (1000 cycles). Li 2 SO 3 will be useful not only for Li 2 S-based positive electrodes but also for the development of materials for all-solid-state batteries.
